@HerrAlias Sieht ja wirklich interessant aus, was ich hier in einer Einführung anschaue: https://youtu.be/cpgnJnRwoLw

Nutzt du es noch? Hat die Schule Data Protection Addendum (DPA) und EU Standard Contractual Clauses (SCCs) https://www.desmos.com/privacy-pdfs/Desmos_DPA_and_SCC_2021-06-17_v3.pdf mit Desmos abgeschlossen?

Leider ist mir keine Alternative bekannt. Ich hätte das gerne in deutsch auf EU Servern als OpenSource. 😁

I've made some updates to my #Desmos simulation of two-source wave #interference.

https://www.desmos.com/calculator/p21l3jxr3e

It now has...
* optional shading to smoothly illustrate the net amplitude in different areas.
* the choice between exact hyperbolic solutions for the maxima or the approximate linear maxima regions typically discussed in double-slit interference
* a single curve/ray at an order/path-difference of your choice even if it's not an extremum

Hallo #fedlz,
ich habe die Polygraph-Funktion von @desmosclassroom
für mich entdeckt und bin begeistert! Das Problem mit #Desmos ist allerdings der Datenschutz. Kennt jemand eine DSGVO-konforme Alternative?

Here’s a #desmos numeracy activity - make 1-10 using the given numbers. #mtbos #iteachmath

Here’s a #desmos activity on systems of linear functions in multiple representations. Starts with comparing visual patterns and then moves to simple situations.

For my #APPhysics students I threw together a #Desmos simulation to illustrate field cancelation inside a spherical shell, a la Newton's "shell theorem".

For visual simplicity this is 2D only! It uses a ring and 1/r force rule as an *analogy* for a spherical shell in our 3D universe with a 1/r^2 force.

As you increase the number of particles in the ring, the results approach the theoretical limit as described by the shell theorem with a zero net field on the interior.

Alright #ITeachPhysics folks, I've finished(?) the #Desmos graph I've been working on during spare moments for a couple weeks:

https://www.desmos.com/calculator/pfzedtpi7y

It illustrates torque & cross product ideas with three corresponding diagrams that you can choose between: (1) a force vector at the point of application with optional component displays, (2) a "flat" common-origin diagram with dot-IN/x-OUT symbol for the torque, and (3) an in-perspective common-origin diagram to help with the 3D-ness of it all.

@Hellobeck 🤣🤣🤣🤣🤣

#Desmos 團隊安靜到大家快忘記他們的存在。

剛剛打開 #Cosmostation 看了一下我的 #Desmos 帳號，還不錯，質押的 節點還在好好的運作中，看來應該要加點 $DSM 進去了，不然，賺的有點慢。

#Desmos 有新聞了耶！

以為 #Desmos 停擺了。

Liebes #FediLZ, ich bin auf der Suche nach Lehrkräften, die #Desmos Classroom Activities im Mathematikunterricht nutzen. Wem darf ich hier folgen? #mathematik #matheedu

I've made a few more updates to my #Desmos graph for illustrating vector dot products.

It's now built in a way that lets you easily change the angle while keeping the magnitudes fixed! You can control the vectors with sliders in the expression list OR with draggable points in the graph area.

Some #desmos #trigonometry repeated practice activities I'm working on. I always appreciate feedback, suggestions, etc. First time posting a desmos on Mastodon! #mtbos #iteachmath https://teacher.desmos.com/activitybuilder/custom/6373e17b46c24efc1cc0384b

@CelesteBancos
That actually sounds better than my well-honed cynicism wants me to admit right now :o)

Thanks for the link -- (and I wonder if that text was already there when I posted the question ...)

I'm occasionally using #GeoGebra for similar things (if I don't plan to share them online), but I like the #Desmos interface better for some of the things I use it for.

Here’s my #introduction post. I’m a high school teacher in the SF Bay Area, with three kids (8, 6.5, and 3.5). Currently, I spend most of my time teaching or parenting. I thought joining this sfba instance might help me connect with more people in the area. I enjoy drinking good #tea, making #Desmos activities (it’s a math teacher thing #mtbos), reading (though mostly just audiobooks these days), #crosswords, music, cooking, hiking, etc.

拿到我的 #DESMOS T-shirt 了，它是一塊棉豆腐。 :7081:

#DSM

@excarnateSojourner
Thanks for finding that! Sounds a bit ambiguous. Schools/universities etc paying to use it sounds much better than selling teacher/student data, and makes more sense students paying. Publishers of course material or school books makes sense, for add-on material to books.
I don't like the sound of "assesment companies", though.

And it looks #Desmos could then become the controller of all related data flows, which I don't like at all.

Needs #decentralization

Discovered #Desmos yesterday,, and their graphing calculator seems seems like a pretty neat tool to explore simple (and somewhat less-simple) functions, series, equations, and even systems of equations. Simple example:
https://www.desmos.com/calculator/lac2i0bgum

...but I don't understand their business model, which probably means "take all the user data and sell to the highest bidder" -- or maybe not? Does anyone know more?
